@jathu and @larryliu0820 , could you help on this issue?

[larryliu0820]

Hello @ManojShanmugamTruminds can you run the following command and attach logs?

python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

[ManojShanmugamTruminds]

Tried below command
python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

@ManojShanmugamTruminds Hi thanks for the quick reply.

Can you do

python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu > log.txt 2>&1

And paste log.txt?

[ManojShanmugamTruminds]

log.txt

[larryliu0820]

  ld: warning: ignoring file '/opt/anaconda3/envs/et_mps/lib/python3.10/site-packages/torch/lib/libtorch_cpu.dylib': found architecture 'arm64', required architecture 'x86_64'

Can you uninstall torch:

pip uninstall torch

And try ExecuTorch again?

[ManojShanmugamTruminds]

Uninstalled pip uninstall torch . Still getting error

[larryliu0820]

Can I get your log.txt again?

[ManojShanmugamTruminds]

log.txt

[larryliu0820]

Hi sorry I don't think you uninstalled torch properly. Please make sure you don't see anything under

/opt/anaconda3/envs/et_mps/lib/python3.10/site-packages/torch/

After you uninstall torch.

[ManojShanmugamTruminds]

Still getting same error

log.txt

[larryliu0820]

Hi can you do

ARCHFLAGS="-arch x86_64" python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

or

ARCHFLAGS="-arch arm64" python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

[larryliu0820]

Are you on mac m1+?

The thing is your pip is installing torch with a different arch flavor (arm64) than what ExecuTorch expects (x86_64). I think your pip or python is not built for your mac.

[ManojShanmugamTruminds]

[larryliu0820]

@ManojShanmugamTruminds ok can you try:

ARCHFLAGS="-arch arm64" python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

[ManojShanmugamTruminds]

Tried this command
ARCHFLAGS="-arch arm64" python -m pip install . --no-build-isolation -vv --extra-index-url https://download.pytorch.org/whl/nightly/cpu

[larryliu0820]

I think your whole environment is messed up. Your pip thinks you are on x86_64 which is incorrect. Can you start a new conda?

Try:

conda deactivate
CONDA_SUBDIR=osx-arm64 conda create -n et_mps2 python=3.11
conda activate et_mps2
bash ./install_executorch.sh
